Description

Working platform for cleaning cultural relics

Technical Field

The invention relates to the field of cultural relic cleaning, in particular to a working platform for cleaning cultural relics.

Background

When the collected cultural relics are unearthed, the cultural relics need to be cleaned for a plurality of times. Particularly, when vessels with special shapes are cleaned, soil in the containing cavities of the vessels needs to be manually cleaned, and rusty spots, oil stains, water stains, sweat stains and the like of the vessels need to be cleaned. Generally, the fixation objects on the unearthed objects are hard and are not easy to be washed off at one time, and metal or hard objects cannot be forcibly removed during washing, so that the unearthed objects are prevented from being damaged due to large external force.

In addition, the existing unearthed cultural relics of vessels need to be peeled off in multiple layers by using a bamboo knife or a wood knife manually, so that the manual operation time is long and the physical strength is high; after the soil is removed from the ware, if oil stains exist, the ware needs to be cleaned after being soaked in soapy water, detergent and the like, and the ware treated by the cleaning agent needs to be rinsed for a plurality of times by distilled water so as to avoid the influence of acid, alkali and other components of the cleaning agent on the ware. The washed ware can be stored after being dried. Therefore, the cultural relics are cleaned in a plurality of working steps, and the cultural relics are carried for a plurality of times during cleaning, so that secondary damage is easily caused. Thirdly, the gaps of copper ware or pottery, etc. which are hidden with dirt are not easy to be cleaned, which is the prior art.

In addition, hard materials which are difficult to remove or are adhered by grease can be softened by matching with organic solvents such as ethanol, acetone and the like and then removed by a scalpel, and hard materials on the surface of the porcelain can be removed by means of grinding, beating and the like by adopting a mechanical electric tool. But still need the manual work to get rid of, but often artifical polishing dynamics is not good to master, easily appears knocking the dynamics big and make the historical relic appear the crackle.

starting the transverse motor 6221 to enable the cleaning head 621 to approach the front end of the cultural relic, adjusting the longitudinal motor 6231 to enable the guide part 7 to be abutted against the inner cavity of the cultural relic, naturally, manually adjusting the guide part 7 of the cleaning head 621 to the front end of the inner cavity of the cultural relic, and adjusting the contact distance between the guide part 7 and the cultural relic by the electric push cylinder 62162 to prevent the cultural relic from being subjected to overlarge abutting force, thereby avoiding damage;

the transverse motor 6221 is started to enable the guide part 7 to be gradually fed to the deep part of the cultural relic inner cavity along the transverse direction, the track of the cleaning head 621 is adjusted according to the position collecting camera 8 of the guide part 7, the cleaning head 621 is enabled to be fed along the cultural relic inner cavity, meanwhile, the cleaning motor 625 is started to drive the plurality of polishing heads 6214 to polish and clean the cultural relic inner cavity, the polishing heads 6214 can be closer to the cultural relic inner cavity through the action of the elastic bodies 6212, and the elastic force of the elastic bodies 6212 acting on the cultural relic inner cavity is set according to the pressure of the cultural relic multiplied by the safety factor and the torque force of the rotating polishing heads 6214, so that the cultural relic cannot be damaged by large impact. The cleaning head 621 of the embodiment can also be used for cleaning the periphery of the cultural relic, and the periphery can not be cleaned due to the fact that the position pressed by the positioning part 5 can not be cleaned, so that the cleaning head 621 can be used for cleaning the cultural relic in a turning way twice;

in the cleaning process, the workbench 4 can be driven to descend by the transmission device 3 until the cultural relics to be cleaned are completely soaked in the cleaning box 61, or the transmission device 3 can reciprocate, so that the cleaned fixed matters flow out along with water flow to achieve the cleaning and cleaning effects, and in addition, the workbench 4 can be used as an independent cleaning workbench 4, so that the cleaned cultural relics can be cleaned.

The workbench 4 for cleaning cultural relics of the embodiment takes into consideration tolerance of the cultural relics and fixings which are not easy to clean, and the fixings which are not easy to clean are cleaned through rotation of the polishing head 6214, so that the cleaning quality is ensured, and the manual cleaning time and physical force are reduced.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
